Water Use and Water Reuse/Recycling in Marcellus Shale 

# Gas Exploration and Production Dave Yoxtheimer - Penn State University Tony Gaudlip - Range ResourcesMarcellus Shale Water Management l October 2010 l 4 

### Marcellus Shale Water Management Tony Gaudlip, Water Operations Manager October, 2010Marcellus Shale Water Management l October 2010 l 5 Requirements Conventional versus unconventional Sources Balancing regulatory considerations with operational flexibility Reuse Surface aesthetics versus downhole performance Storage Tanks, pit, impoundments... Transfer Reducing truck traffic while ensuring integrity 

## Key PointsMarcellus Shale Water Management l October 2010 l 6 Substantially Larger Volumes 4-6 million gallons per well Increased Pump Rates 80- 100 bpm 

## RequirementsMarcellus Shale Water Management l October 2010 l 7 Simplified Fluid Design Slickwater with corrosion inhibitor and bactericide Water Quality Shale permeability Production mechanism Water mobility Challenge conventional rules of thumb 

## Requirements

Parameter Conventional Limits Considerations pH 6.0 to 8.0 Fluid Stability, Scaling Chlorides <20,000 mg/L Fluid Stability Iron <20 mg/L Fluid Stability Ca, Mg, Ba, SO 4 , CO 3 , ... ƒ (P,T,pH) (+/- 350 mg/L) Scaling Bacteria Count <100/100 mg/L Bacteria Growth Suspended Solids <50 mg/L Skin Oil & Soluble Organics <25 mg/L Fluid Stability nanodarcy, nD, 1 x 10 - 9 D

## Reuse Range Resources Reuses 100% of Our Flowback Potential Downhole Issues:  Fluid Stability  Bacteria  Scaling Non - issues - Supported by well performance TDS Build - up Concerns  Not an issue because of required dilution Known Surface Issues...Aesthetics  Solids  Bacteria (anaerobic)Marcellus Shale Water Management l October 2010 l 14 

## Reuse Keys to Remediating Surface Issues  Solids – Clarification  Bacteria (anaerobic/SRBs)

– Remove Food Source

– Chlorinate

– Maintain with Aeration Pre -Aeration Post-AerationMarcellus Shale Water Management l October 2010 l 15 

## Storage Impoundments vs. Tanks The Goal is Maintenance Double Liner System w/Runway Permanent Fill/Withdrawal Manifold System Under- Drain Catch Basin System with Leak Alarm Front- End Weir Tank Battery for Solids and Condensate CaptureMarcellus Shale Water Management l October 2010 l 16 

## Storage Aeration System Bird Netting Remote Level Monitoring System Security/Privacy Perimeter FencingMarcellus Shale Water Management l October 2010 l 17
